Well, it is a very high-end item. For that I think it's not too hard to make. Apart from that, I don't understand why you complain about this but take no issue with prospecting. I'd rather craft ten primal staves than having to search for a rare mineral vein. First, the grind can be reduced significantly by clever organization, just as in GT's occasional crafting grind, and second, you can be certain of the outcome after a given amount of time. The really grindy thing in Thaumcraft is moving aura nodes.This was valuable info Ieldra.
Crafting this thing took bloody forever. So many staff cores :\ no wonder people say GT works well with TC, they're both pretty grindy sometimes.
Ah, I forgot that about silver caps. Since I don't have the 375-capacity staff (I found out about that in my test world after I had already made my staff) I have something to look forward to...For what its worth, you can use silver caps instead of gold for an extra efficiency boost in the four elemental primals. Requires discounts from clothing though, I had void for the job.
BTW, you already visited the Outer Lands, right? Did you have a better - i.e. easier to acquire - source for Alienis essentia than ender pearls? I just used up almost all my remaining pearls for the Eldritch Eyes. The other void-relevant aspects - tenebrae and vacuos - are easy to acquire from very common sources (I use silicon dust - ultimately sand - and trashcans - ultimately wood and stone), but alienis has been a problem ever since I started with the void-aspected stuff.
Sidenote: Infitech derp #1: I had set up my ebf to make a few stacks of steel overnight but forgot to connect more than one drum of oxygen.... grr...*slaps self*
